That's a clip from "Home Movies" which was on UPN and the Cartoon Network for awhile. Thanks to the DVD and the internets I've been watching a lot of it lately. The show was produced by the company Soup 2 Nutz which also did "Dr. Katz" and another education show by called "Science Court". Those were some really good shows.
One of my favorite things about that show and other shows like it such as Nick Park's "Creature Comforts" are their playful use of language.
For the Soup 2 Nutz stuff, the focus on language exists because most of the show is recorded in an improvisational manner and then carefully reedited. In "Creature Comforts", audio teams go all over the UK to conduct interviews in a relaxed natural context with average everyday people.
When people speak in real life, they hesitate, repeat words, change sentence structure mid sentence, and interrupt and overlap with other speakers. Almost all TV shows and movies abandon this mode of speech in favor of cleaner and more presentable stage speech.
